Plain-English summary

Daimler Buses North America (DBNA) is recalling 96 model year 2010 Orion VII transit buses manufactured between November 2010 and January 2011. These vehicles are equipped with Cummins ISB, ISX, ISC, or ISL diesel engines. The recall addresses a defect in the V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (DOC)/diesel particulate filter (DPF).

The T-bolt within the clamp assembly can fracture and fail when subjected to stress or load. If the bolt fails, the clamp may loosen, causing the inlet or outlet sections to disconnect from the DOC/DPF housing. This disconnection allows hot exhaust gases to vent before exiting the tailpipe, creating a risk of combustion and fire. In some applications, if both clamps fail, the DOC/DPF housing may detach completely, creating a road hazard.

DBNA is working with Cummins to identify and notify owners of this recall campaign, which began on October 12, 2011. Repairs will be performed by authorized Cummins dealers free of charge. Owners may contact Cummins at 1-812-377-5000 or DBNA at 905-403-1111 for more information.
